Heart Rate and Exercise
Literature Review
The human heart is a very complicated organ, with the main purpose to pump life sustaining blood throughout the human body. It also supplies oxygen and nutrients to all areas and clears harmful waste from the body.
The heart is made up of cardiac muscle which beats on its own. According to the article ‘heart ‘which was written by The National Geographic the heart will slow down or speed up depending on how the body is being used. This is done by nerve signals which are being sent from the brain.
This indicates that in order for the body to keep on going, the heart will need to pump more blood through the body when say doing exercise due to the muscles being used on a higher level, which will then lead to more beats per minute, if the body is used to this type of exercise then the heart will not beat as many times due to each heartbeat being able to pump more blood (the body will be less likely to get tired easily), this is for both resting heartbeat rates and when doing activities. This is suggested in both articles; the effects of exercise on the heart and how does exercise affect you heart?.

When you are resting the heart does not need to pump as much oxygenated blood to the body. The amount of exercise you do will have an impact on how long it takes for your heart rate to get to its average baseline.
During exercise
During any physical activity the heart automatically pumps more blood to the working areas in order for the muscles to work (it depends on how intense the activity is as to how much the heart will pump) this then makes the heartbeat rate higher because there is more blood needed therefore more beats per minute are used, if the person is fit then the
